Answer:
32.9%
Explanation:
<u>The mass of water </u>present in the original sample can be calculated by the substraction:
- m H₂O = sample mass before heating - sample mass after heating
- m H₂O = 8.24 g - 6.20 g = 2.04 g
The <u>percent by mass of water</u> can be calculated with the formula:
- Water Mass / Original Sample Mass * 100 %
* 100% = 32.9%
Answer:
FIGURE 5.9 The arrow shows a second way of remembering the order in which sublevels fill. Table 5.2 shows the electron configurations of the elements with atomic numbers 1 through 18.
Element Atomic number Electron configuration
sulfur 16 1s22s22p63s23p4
chlorine 17 1s22s22p63s23p5
argon 18 1s22s22p63s23p6

<em>Brainlilest </em><em>me </em>
Answer:
Binding affinity measures the strength of the interaction between a molecule to its ligand; it is expressed in terms of the equilibrium dissociation constant; and the higher value of this constant, the more weaker the binding between the molecule and the ligand is. On the other hand, small constans means that the interaction is tight. So "C" binds most tightly to the enzyme and "D" binds least tightly.
Answer:
Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.
Given :
The 52.06 grams of carbon dioxide.
To find :
The moles of carbon dioxide.
Solution:
The mass of carbon dioxide = 52.06 g
The molar mass of carbon dioxide = 44.01 g/mol
The moles of carbon dioxide:
1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.

Answer:
All around you there are chemical reactions taking place. Green plants are photosynthesising, car engines are relying on the reaction between petrol and air and your body is performing many complex reactions. In this chapter we will look at two common types of reactions that can occur in the world around you and in the chemistry laboratory. These two types of reactions are acid-base reactions and redox reactions.
